Q2: What is the price and local procurement procedure in Bangladesh (BD)?

Answer: In Bangladesh (BD), the regular market price for the DLAB SafeVac 4L Vacuum Aspiration System ranges between BDT 125,000 and BDT 140,000, depending on current promotional discounts, included hand operator attachments, and regional supplier packages. For official corporate price quotes, institutional tenders, and direct stock availability in BD, contact authorized laboratory distributors such as Federal Scientific Mart (fsm.com.bd).

Q3: What warranty coverage and technical support are provided in Bangladesh?

Answer: The DLAB SafeVac comes standard with a 12-month (1-year) factory warranty covering manufacturing defects, internal vacuum pump failures, and electronic level sensor faults. Authorized local distributors like Federal Scientific Mart provide local technical support, spare parts replacement (such as 4L PP bottles, hydrophobic filters, silicone tubing, and adapters), and routine maintenance across Bangladesh.

Q4: How does the level sensor system prevent waste bottle overflow?

Answer: The SafeVac bottle lid features an integrated level sensor that continuously detects the waste liquid level inside the 4L bottle. When liquid reaches maximum capacity, the sensor automatically shuts off the internal vacuum pump and activates an audible and visual warning alarm. This dual safety mechanism eliminates the risk of corrosive or biological liquids overflowing into the pump motor or laboratory bench.

Q5: Which hand operators and channel adapters are compatible with the SafeVac?

Answer: The SafeVac system features a quick-connect ergonomic operator handle that supports multiple interchangeable aspiration adapters:

• Single-channel adapters: Compatible with standard micropipette tips (200 microliter or 1000 microliter) or stainless steel needles for aspirating from culture dishes and test tubes.

• 8-channel adapters: Designed for rapid, simultaneous liquid aspiration from 96-well microplates and ELISA culture plates.

Q6: How do you operate and execute liquid aspiration with the SafeVac step-by-step?

Answer:

1. Connect the silicone tubing, 0.22 um hydrophobic filter, level sensor plug, and hand operator to the 4L waste bottle assembly.

2. Plug in the power supply and turn on the main power switch on the base unit.

3. Turn the vacuum adjustment knob to set your desired suction pressure (from 0 to 600 mbar).

4. Attach the appropriate single-tip or 8-channel adapter to the ergonomic hand operator.

5. Press the hand operator lever/trigger to aspirate liquid supernatant directly into the 4L collection bottle.

6. When the 4L bottle reaches full capacity, the level sensor automatically stops the vacuum; turn off the power, unscrew the bottle cap, and autoclave or safely dispose of the biohazardous waste.

Q7: What decontamination and sterilization protocols apply to the SafeVac?

Answer:

• Autoclavability: The 4L polypropylene waste bottle, lid, silicone tubing, hand operator, and tip adapters are fully autoclavable at 121 degrees C (15 psi / 1 bar) for 20 minutes to eliminate biohazardous pathogens.

• Inline Filter: The 0.22 micrometer hydrophobic filter cannot be autoclaved; replace it if it becomes clogged or wet.

• Base Unit: Wipe down the compact pump housing with 70% ethanol or mild surface disinfectant.

Q8: What primary applications benefit from the SafeVac Aspiration System?

Answer: The SafeVac is an essential tool for cell culture and molecular biology workflows, including:

• Aspiration of media supernatant from cell culture dishes, flasks, and multi-well plates.

• Washing steps during ELISA assays and western blot membrane processing.

• Removal of liquid reagents in RNA/DNA extraction protocols.

• Disposal of biological fluids in containment facilities and laminar airflow cabinets.

Q9: How do you replace consumable parts and perform routine maintenance?

Answer:

• Tubing & O-Rings: Periodically check silicone tubing for cracks or discoloration; replace worn seals to maintain vacuum integrity.

• Filter Care: Replace the 0.22 um hydrophobic filter regularly to ensure unimpeded airflow and keep the internal vacuum pump protected from biological aerosols.

• Cleaning Level Sensor: Clean the metallic probe on the bottle cap assembly after each use to ensure reliable liquid detection.

Q10: What items are included in the standard factory package when purchased?

Answer: The complete factory package includes:

• SafeVac main base unit with built-in oil-free vacuum pump
